The anode rod  in your A.O. Smith brand water heater is located on top of your tank. When you are facing the front of your water heater, the sacrificial magnesium or aluminum anode is located at the back, between the cold and hot water connections. Refer to your water heater’s user guide for more information.

    My AO Smith water heater has 2 anode rods. I bought a powered rod from you guys and noticed this during the install. Do I need to remove the other anode rod?

      Hello Christian, you don’t need to remove the second anode rod.
